Antineutrophil cytoplasmic antibody–associated vasculitis with initial gastrointestinal symptoms: case series and literature review
Key Points
This research aims to address the rarity and misdiagnosis of gastrointestinal symptoms in antineutrophil cytoplasmic antibody-associated vasculitis (AAV).
Conducted a case series analysis of AAV patients with initial gastrointestinal symptoms.
Performed a literature review to assess prior findings related to AAV symptoms.
Evaluated the involvement of gastrointestinal, pulmonary, and renal systems in AAV cases.
Identified significant cases where gastrointestinal symptoms preceded AAV diagnosis.
Highlighted the importance of recognizing gastrointestinal symptoms for early detection of AAV.
Reinforced the need for thorough assessments including pulmonary involvement in suspected AAV cases.
Abstract
Gastrointestinal symptoms in AAV are rare, and misdiagnosis remains a concern. Early detection requires assessing gastrointestinal, pulmonary, and renal involvement.
